FIG. 1.

Structure of the cubic ( or Zr) unit cell, with being the lattice constant. White and dark circles represent O and M atoms, respectively. M atoms are at the face center sites of an external cube and O atoms at the simple cubic sites of an internal cube.

FIG. 2.

Phonon spectra along the direction for cubic (solid circles) and cubic (solid triangles), with ( or Zr).

FIG. 3.

The phononic band structure of a multilayer stack, with , calculated using first-principles DFT (solid circles) and by solving the acoustic wave equation [Eq. (2)] in the continuum limit using parameters obtained from first-principles calculations (solid line).
